Benefits of technology

[0042]By virtue of the present invention, a solution is applied including: acquiring a generator polynomial matrix according to a generator polynomial and the number of digits of the data to be checked and generating a CRC code using a formula for calculating the CRC code of the data acquired according to the generator polynomial matrix, initial CRC register value and the data to be checked, and as a result, the problem that the load of registers is increased when the number of digits of the data needing to be checked is not the nth power of 2 in the conventional art is solved, and the effect of reducing the load of registers is achieved.

Problems solved by technology

In the transmission and storage process of data, the received data may be inconsistent with the sent data due to external interference and other reasons.

Abstract

The invention discloses a method and an apparatus for data check processing, the method comprises: acquiring data to be checked; acquiring a first polynomial matrix F according to a generator polynomial; acquiring a second generator polynomial matrix Fi according to Fi=Fi, wherein i is the digit of the data; generating a CRC code of the data from the second generator polynomial matrix Fi, initial CRC register value X(0) and the data; and sending the data and the CRC code to a receiver for being checked by the receiver.

Description

[0001]This is a continuation of International Application PCT / CN2010 / 076202, with an International Filing Date of Aug. 20, 2010, which claims priority to Chinese Application No. 201010114360.6, filed Feb. 23, 2010, each of which is incorporated by reference.FIELD OF THE INVENTION[0002]The invention relates to the field of data transmission in communication systems, in particular to a method and an apparatus for data check processing.BACKGROUND OF THE INVENTION[0003]In the transmission and storage process of data, the received data may be inconsistent with the sent data due to external interference and other reasons. In order to ensure the correctness of data transmission, generally, some encoding and checking methods are applied in the data transmission process. The realizing methods of checking comprise: parity check, cyclic redundancy check (CRC) and so on, wherein the CRC is widely applied in the communication field and other fields due to its high efficiency and performance.[000...
